If you think a $199 laptop is too good to be true, you’re right. Radio Shack has been offering the “Acer Aspire” for this price — with a big catch: You have to sign up for a two-year, $60-a-month 3G Internet connection. This is a very high-speed connection you can use anywhere, and some say it’s worth the price, but this contract adds $1440 to the cost of the laptop. We’ve seen netbook computers – similar to laptops — for $300 from ASUS.
